Interventional
Description of intervention(s) / exposure
The primary aims of this study are to examine the acceptability and safety of app-based cognitive training as well as the potential benefits of training on objective cognitive outcomes for young people with depression, when compared with an active control.

The primary intervention is a commercially available cognitive training smartphone app. This involves playing interactive 'game-like' cognitive exercises, which engage a range of cognitive domains including attention/vigilance, processing speed, learning and memory, and various executive functions (e.g. inhibition and flexibility). There is recent evidence to support improvements in untrained domain-specific cognitive tasks following intensive training using this app (i.e. 15 minute training sessions five times per week over 10 weeks) when compared to an active computer game control condition. Adherence will be monitored using software built into the app, with utilisation reports for each participant sent to the research team monthly.

Participants that are randomly allocated to this intervention will train on the app individually on at least 4 separate days per week (at least 15 minutes per occasion) over the 8-week intervention duration. Participants will guide their own training program and select their own training exercises. All participants will receive a weekly reminder text to encourage app use. This intervention protocol was informed via focus groups with young people with mental health concerns. All participants will be asked to attend a baseline assessment, start-up meeting (to provide the participant's app allocation and set up a user account, representing the start of the intervention) and post-intervention assessment.

Comparator / control treatment
The control condition in this study is a commercially available gratitude diary app. This app allows participants to log multiple daily personalised 'gratitudes' (i.e. record the people, places, experiences, etc, that the person is thankful for in their life). The app includes various features to increase user participation and motivation, including uploading photos, affirmations (i.e. quotes that are shown daily) and a calendar-tracking function. Similar to the intervention group, control participants will be asked to use the app on at least 4 separate days per week over the 8-week intervention duration and will receive a weekly text to encourage app use. This condition is designed to control for non-specific factors such as increased screen time on, and structured engagement with, health-related apps.

Summary
Brief summary
Subjective and objective cognitive impairments are core features of youth depression. These are experienced as distressing, are associated with poorer functioning and may limit the benefits of psychological treatments such as cognitive behavioural therapy. Based on effectiveness in improving cognitive function in conditions such as schizophrenia and attention-deficit/hyperactivity disorder, research has begun to investigate cognitive training as a potential approach to improving cognitive functioning in depression. A recent meta-analysis of nine trials of cognitive training for adults with depression found significant post-training improvements in attention, working memory and global cognitive function. Nevertheless, few studies have explored the potential effectiveness of cognitive training apps in young people, especially with depression. The aim of this study is to investigate the acceptability, safety and potential effectiveness of app-based cognitive training relative to an active control for young people with depression receiving treatment in a primary health care setting (headspace).
